It is a type of the armored doors that comprises additional thermo-insulation rigs as well as the moisture-resistant UMIDAX boards and is aimed at use outdoors. It is suited for the environment (or private homes, cottages to be fitted with ) with significant variations of temperature. Testing revealed thermal conductivity as big as 1,2 W/m2 K, on par with the conductivity figures showed by testing of our plastic windows. Consider this type should you face condensation issues.
THE DOOR JAMB is made of 80mm wide and 2mm thick closed steel profiles. The folded L-shaped profile is used for welding of the door threshold – a solution introducing the door sealing with a double gasket (one on the outside and another on the inside). A standard configuration includes the jambs insulated by applying polystyrene foam.
DOOR LEAF is made of 40mm wide and 2mm thick closed steel profiles. In order to protect the door against deformation and to enhance its durability the leaf is reinforced with two horizontally welded steel profiles. The exterior surface is 1,5 mm of thick steel sheet coating.
We employ 3-stage insulation installation technique. For the 1st stage we use the 2-component foam made specifically for THE DOOR LEAF INSULATION. The foam was thought up to increase in size inside the leaf’s closed steel profile. At the 2nd stage a special thermal insulating film is glued together with the aluminum foil. The latter covers the whole of the metallic section of the internal surface of the door leaf thus constituting the basis for a precise division between that section and the cold bridge. At the final stage two more rock-wool layers of 2 cm thick in the door for better soundproofing as well as thermal capacity are added.
The glass package combining three layers of 4 mm thick per layer (totaling 36 mm). A Standard configuration either a transparent or brown-tinted glass unit. To view more of the glass unit shapes and the patterns we offer please refer to the section «Carvings» of our catalogue.
Italian DOOR HINGES of 20mm of diameter with journal-bearings ensure extra smooth lacing and additional chromium-plated covers for hinges are available on demand.
THE CLADDING PANEL UMIDAX (included for the use in conjunction with our standard exterior doors) is a moisture-resistant wood fibber board. You pick any option of a wide range of both RAL palette colors and patterns capable of satisfying even the most demanding customers.
LOCKS are included on your request. The locks are categorized as the grades 6&7 according to security classification for locking systems. We offer the locks by such brands as e.g. “MOTTURA”, “DORMA”, “EVVA” among other names.
Regarding the maximum thermal insulation we would like to kindly warn our customers against installing security locks in your doors since that leaves the insulation vulnerable enough for the cold to percolate through the lock, thus breaching thermal protection inside the leaf.
